Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.
Remember that everything is allegory - perceived activity in the neural networks of the brain are considered by mainstream scientists as the source of an impulse - this is not so, the reflected result of conscious possibilities are projected and reflected within the brain. Everything external that is perceived as seperate from conscious projection is a reflection of allegorical form and mass - frequencies, images, vibrations, focus and intent are created within antimatter and exist as possibilities. These possibilities are realized by quantum wave collapse.

Quite simply, as you work through each discipline you will see every time that fear doesn't exist, it is nothing more than a perceived minus based on a previous failed attempt to discover the allegorical representation of a blockage within your subconsciousnes that presents itself for reflection through a person, object or thing (allegory).
You will see fear for what it is - the falsely constructed belief structure that reflects itself through things and experiences. It exists only as a concept that can project and reflect itself through others, the more you focus on it, the more you will see it reflected in front of you.
Quite clearly, no matter what the discipline fear will always project and reflect a negative, unwanted experience. Fear in chemistry and in relation to Love is not going to bring any rewards is it? You really do not need to be a wizard to understand that concept.
As the origin of all externally reflected atomic form and mass is formless, all visible matter is a form of allegory. This allegory is viewed as a centrally focused mirror image reflection in form and mass, is merely light and colour reflection from the void of frequencies you 'set your heart on'.
As allegorical reflection is the real truth of what you see and experience, you will come to see the true origin of clichés and expressions. There is nothing more obvious than the conscious allegorical expression of itself as viewed through the discipline of 'Chemistry'. Infact it would be the most appropriate of all disciplines to note how many expressions for love are chemistry or physics based - we were on the same wavelength, the vibrations were good, sparks flew, there was chemistry between us, good energy, high frequency understanding, nothing went over our heads, she was grounded. Oh there are far too many to write - the subject of a book indeed. Watch this space - or to be more technically correct - watch this space!
Do not allow fear to keep you trapped in your Plato's Allegorical Cave. The light IS at the end of the tunnel, it is shining brightly within you, and you must dig deep to break free and bask in the wisdom of awareness of all that was, is and shall be.
